The information in inlet flow is cached in routing unit, can be with message team when carrying out inlet flow caching
The form of row preserves inlet flow in the buffer, can also other forms progress record preservation one by one；
Step S53：The status data of extraction source application cluster, and save as data snapshot.State
Data migration unit extracts Extract services by calling the data of source application cluster, and source is applied
The status data preserved in Cluster Database, disk file and caching exports as data snapshot, and
Keep in status data migration units；
Step S54：Data snapshot is loaded, and data snapshot reverted to be saved in after status data
In target cluster.Status data migration units are loaded by the data of invocation target application cluster
Load is serviced, and the data snapshot kept in status data migration units is loaded and state is reverted to
After data, it is saved in intended application cluster；
Step S55：The inlet flow of caching is returned into intended application cluster.Open inlet flow it
